Appiication April 2, 1947, Serial No. 738,872

1 Claim. 1

This invention relates to new and useful improvements in brushes and more particularly to chimney brushes.

The primary feature of the present invention is to provide a pair of brushes held back to back by adjustable spring means whereby the brushes can be so placed together under tension and inserted in a chimney flue where the bristles of said brushes will bear outwardly against the walls of the flue.

Another important feature of the present invention is to provide a device of the character referred to including means whereby the brushes may be worked up and down in a chimney flue for cleaning said flue.

A further feature of the present invention is to provide a chimney brush of the class described that is adapted to be conveniently disassembled to provide a small and neat article which may be conveniently stored or packed for shipment.

A still further feature of the present invention is to provide a chimney brush that is simple and practical in construction, relatively inexpensive to manufacture and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a side elevational view of the chimney brush applied to a chimney flue;

Figure 2 is an enlarged sectional view taken on the line 2-2 of Figure 1, and

Figure 3 is a group perspective view of the present invention.

Referring now to the drawing in detail, wherein for the purpose of illustration, I have disclosed a preferred embodiment of the present invention, the numerals 5 and 5a represent a pair of channel shaped members preferably of metal and placed back to back in a spaced apart relationship.

The wooden heads 6 of a pair of brushes designated generally by the numeral 7 and having bristles s, are placed in the respective channel members and are held thereto by bolts 9 slidably extending through the corners of the channel members and of the brush heads.

The bolts 9 are threaded at one end In to receive nuts H, and coil springs l2 loosely carried on the bolts extend horizontally between the opposing backs of the channel members.

Extending horizontally between the upper end of channel members 5, 5d at substantially the center thereof is a removable shaft !3 which is slidably secured between said channel members,

said shaft being adapted to receive the oppositely inturned hook ends I l and i5 terminating downwardly from opposite ends of a coil spring I6 carried by a closed loop I! at the end of a pull wire I8.

In operation of the device the brushes and channel members are forced toward each other and the device with the brushes 1 thereby tensioned by the coil springs 12 is inserted upwardly into a chimney fiuc. The pull wire I8 is extended downwardly for attaching to the rod l3. The hooks M and l5 engage rod or shaft I3 and the handle is pulled upwardly so that the brushes .contact the walls of the chimney.

The process may be repeated until the chimney is cleaned, or the brushes and pull wire l8 may be inverted so that the brushes may be pulled downwardly through the chimney in an obvious manner.

In view of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shown and. described a preferred embodiment of the invention the same is susceptible to certain changes fully comprebended by the spirit of the invention as herein described and the scope of the appended claim.

What I claim is:

A chimney brush comprising a pair of rectangular channel members, a pair of bristle brushes having rectangular backs fitting in said channel members, bolts slidably extending through the corners of said members and backs and slidably holdin said members together in facing relation and the backs of the brushes centered relative to the channels in said members, coil springs on said bolts between said members acting to yieldingly separate the members and maintain the said backs seated in said channels, and a pull member detachably attached to said members between the same and adjacent corresponding end edges thereof.
